A postdoctoral research associate position is available for electrochemical and chemical engineering research on redox flow cells based on novel electrochemistries such as the aqueous-soluble organic couples described in  and . The position is for one year and may be extended for a second year if justified by performance and continued funding.
This research project is a collaboration between the materials group of Prof. Michael Aziz in the School of Engineering and Applied Sciences (SEAS), the theoretical chemistry group of Prof. Alán Aspuru-Guzik at the University of Toronto, the experimental chemistry group of Prof. Roy Gordon of SEAS and the Department of Chemistry and Chemical Biology, and the hydrodynamics group of Prof. Shmuel Rubinstein in SEAS. The researcher who takes this position will perform research in collaboration with others in the Aziz laboratory to design, build, and characterize small redox flow cells based on chemicals designed and synthesized by the collaborating chemists. S/he will develop an understanding of the performance and loss mechanisms of all aspects of cell operation [3,4,5], and innovate on electrode and cell design so as to uniquely identify loss mechanisms, enhance performance and reduce losses [6,7]. Relevant phenomena are expected to include reversible and irreversible side reactions including molecular decomposition; Faradaic redox kinetics at flat and structured electrodes; mass transport to and from electrodes; ionic conduction within porous media; electron conduction through electrodes; membrane Ohmic losses; species crossover; osmotic effects; intrinsic porosity and flow field design for electrolyte flow through porous electrodes; and long-term degradation mechanisms. Among the methods s/he will utilize to understand these phenomena are quantitative electrochemical impedance spectrometry; the design and implementation of reference electrodes in operando ; and the development of methods to isolate and evaluate losses from individual components [4,7]. S/he will work with the multi-group team on many aspects of these studies and will supervise graduate and undergraduate students in the performance of some aspects of this research.
-Demonstrated strong experimental skills.
-Pragmatism in meeting project deadlines.
-Demonstrated ability to work collaboratively with others.
-Availability to begin the position on or before May 1, 2020.
-All the work for a Ph.D. in Chemical Engineering, Electrochemistry, or a related field should be completed by May 1, 2020.
-Familiarity with some of the methods mentioned above is an advantage, but the ability to rapidly learn and implement new methods is more important.
